Drive Sprocket Rollers
Rubber Track Loaders use rollers on
each drive tooth of the two drive sprock-
ets. These rollers help minimize friction
between lugs on the track and the
sprocket. Sprocket rollers should be
treated as wear items that are inspected
regularly and replaced as needed.
The rollers (1) rotate on steel pins (2),
limiting wear to the inside of the rollers.
As they wear, the rollers become thinner,
but will continue to function and perform
as long as they are rotating.
Visually inspect rollers every 50 hours
and replace any that show signs of
cracking or wear-through.
In order to replace sprocket rollers, the
drive sprocket must be removed from
the undercarriage. Track removal is rec-
ommended and makes the replacement
process more efficient, but is not
required. For specific instruction regard-
ing roller replacement, consult your
machine specific service manual.
